Write an expression that represents 2 more than 4 times a number
pav-90 [236]
Go backwards with the problem. 4 times a number would mean 4x. 2 more means you're adding 2. so your answer should be 4x+2

So hmm check the picture below

\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
x=3\\
y=1
\end{cases}\implies 1=k3\implies \cfrac{1}{3}=k
\\\\\\
thus\qquad \qquad y=\cfrac{1}{3}x

the radius of the base is 4 inches and its height is 6 inches what is the surface area of the cylinder in terms of pi
wolverine [178]
Answer is 80pi
Step by step

To find lateral_area = (2 * π * r) * h

Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi

base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi

Total surface area in terms of pi = 32+48
= 80pi
